Every year, the Third Coast International Audio Festival calls on radio pros and radio rookies to create a short doc. There are specific parameters - it can only be two to three minutes, for example - but the theme takes on a new life each round. Audio makers this time around will be following in some big footsteps as Studs Terkel serves as the inspiration for the 2015 Short Docs Challenge. We talk with Third Coast International Audio Festival Managing Director Sarah Geis about the details of the challenge, and hear past examples. (Flickr/cogdogblog)
